A process produces a composite component, which includes an insert and a plastics part made of a thermoplastic polymer. The plastics part at least partly encloses the insert. The process includes (a) placing at least one part of the insert or the insert into an injection mold, (b) closing the injection mold, and (c) injecting the thermoplastic polymer into the mold thereby overmolding the insert at least partly. The insert is modified before placing it into the injection mold or the insert is modified in the injection mold before the injection mold is opened to remove the composite component.

A method may be employed to produce a variable-length steering shaft. The method may involve positioning a shaft core within a mold cavity of an injection molding tool coaxially with respect to a mold surface that delimits a toothing region, injecting molten plastic into the mold cavity between the shaft core and the mold surface of the mold cavity, removing a toothed shaft from the injection molding tool after the molten plastic has solidified, providing a hollow shaft and axially inserting the toothing region into an internal toothing of the hollow shaft. To make it possible to provide an improved sliding coating with the least possible manufacturing outlay, the injection of the molten plastic may be performed from one axial end region of the mold cavity.

Apparatus and method of forming connector brackets for irrigation laterals along a prefabricated lay-flat pipe and lay-flat pipe with such connector's brackets, wherein an opening is formed at one wall of the premanufactured pipe, a separation means is positioned inside the pipe opposite the opening while separating the one wall from the second wall of the pipe, and an injunction molding is performed into a mold cavity, in order to form the bracket affixed to the one wall of the prefabricated pipe and around the opening.

A molding system for applying moldable material to a pipe. An elongate mold has at least one elongate mold member movable relative another elongate mold member between open and closed positions. In the closed position, the mold may define an elongate vent between the mold members that extends along the longitudinal axis of the mold. Air in the mold cavity displaced by moldable material received into the mold cavity vents through the elongate vent along the longitudinal axis of the mold. The mold can include a positioner that positions the mold members in the closed position while the mold is filled with the moldable material. The positioner also allows movement of the first mold member toward the open position to partially open the mold as the moldable material cures to reduce forces imparted upon the mold due to expansion of the moldable material during curing.

An air duct assembly attachable to a receiving port includes an air duct with an inner surface and an exterior surface connected to one another at a coupling fixture. A seal is connected and bonded to the coupling fixture. The seal extends axially from the coupling fixture and has a tip with an inner diameter smaller than the coupling fixture's inner diameter. A shell is connected to the coupling fixture and the seal. The shell extends axially from the seal and is connectable to the receiving port.

The production of multicomponent parts (4) which include a functional part (3), in particular a hollow needle, onto which a plastic molding (2), in particular a syringe barrel (2), is molded. In order to be able to convert the injection molding device quickly and conveniently, the device has a changing device (11), by which it is possible optionally to move functional part holders (7, 8, 9), matched to different types of functional parts, and/or a functional part holder (8) and a placeholder element (10) into the use position thereof in front of a mold cavity (6) of the injection mold (5) of the injection molding device (1).

A light-weight gear including: an annular tooth portion made of metal; a shaft extending along a central axis of the tooth portion and made of metal; and a coupling element configured to couple the shaft to the tooth portion and made of a resin, in which a joining part between the shaft and the coupling element and a joining part between the tooth portion and the coupling element are provided with irregularities configured to be engaged with one another in a circumferential direction, and corners of the irregularities are rounded to release a stress. Also, provided is a manufacturing method of a light-weight gear including: disposing the tooth portion and the shaft in a mold and injecting a molten resin into a cavity of the mold, thereby simultaneously performing injection molding of the coupling element and joining the coupling element to the tooth portion and the shaft.

A method of making a medical device includes holding a spacer tool by a slot of a mold, and accommodating a portion of a first tube by a lumen in the spacer tool, wherein a region of the first tube is inside the mold cavity and outside the spacer tool, and an end of the first tube is in engagement with an end of a first lumen-defining section of a first core pin. The spacer tool includes a first section located in the mold cavity when the spacer tool is held by the slot of the mold, the first section of the spacer tool being configured to define a cavity to be formed circumferentially around a part of the first tube inside a hub to be formed, wherein the part of the first tube is different from the region of the first tube.

A method for applying a label to a container particularly suited for applying a polypropylene label to a polypropylene cup as it is moulded. The resultant container is made of a single type of plastic allowing it to be easily recycled. The mould used to produce the container has been designed to hold a label in place and stretch a portion of the label so it stays in place before injecting the plastic to form the container.

A cartridge for a medium to be dispensed includes a head part having a dispensing outlet and a film forming a cartridge wall, with the film bounding a cartridge chamber for the medium to be dispensed, extending at least partially in a longitudinal direction of the cartridge and having a front end that is connected to the head part. The head part has a collar, the collar surrounding the dispensing outlet in a radially outer region of the head part and extending in the longitudinal direction. The front end of the film is sealingly and non-releasably connected to the collar of the head part. The collar of the head part has an inner surface extending in the longitudinal direction and includes at least one projection projecting radially inwardly.
